How many children will be plowed over before this lunacy will stop? How will the AI decide if the child's life is worth it when it might cause an accident to swerve, assuming the car sees the kid in time (known problem with the systems so far). Will the government be actively involved in certifying a system that chooses to run over a toddler "for the greater good"?
Also, how do you tell the car where to park on your driveway, how to avoid flooding, how to navigate tire level obstacles? How to prevent the car from taking you up a road closed in bad weather and stranding you? You hear stories of clueless people following GPS into danger, what happens when the car does it itself and you can't stop it?
